Numerical Wake Prediction Methods for Submerged Appended Bodies, A Literature Survey.

Abstract

The numerical methods relevant to the wake prediction of submerged appended bodies for the purpose of predicting full scale wake are surveyed. The main flow features are first described and the numerical techniques used to predict them are then discussed. A complete solution of the flows around submerged appended bodies is beyond the reach of the state-of-the-art, both numerically and computerwise. For this reason, two approaches are recommended to be pursued simultaneously. One approach is for immediate applications and the other approach for long-range research. For the first approach, the momentum integral method is recommended due to its relative simplicity and its flexibility to adapt to experimental data. For the second approach, a numerical procedure no less sophisticated than the one by solving the partially parabolic Navier-Stokes equations with the Kappa Epsilon turbulence model should be considered.
